[Amps] anode connectors

[peter chadwick]

The places I've seen porcelain caps used were ones where tubes were exposed, and the porcelain caps were for safety reasons. How much you need to dissipate is an interesting question, since conduction along the relatively thin wires from the actual plate to the cap  can't be that much, unlike the big glass tubes (4-125, -250, -400, 3-500Z) which had a substantial piece of metal to hold the plate.

The UK manufactured KW1000 had connectors made of hard copper strip by the metal bashing company that was used: they never got hot enough to anneal soft. I'd go down that route - some 18 gauge 3/8 or 1/2 inch wide copper strip, hammered well to work harden it and bent to be a snug fit.

 Plate cap.
 
 The porcelain caps dont dissipate heat and Im surprised Ameritron didnt use 
 aluminum heat dissipators as with their 3-500 amps. Even the AL-572 uses 
 Chinese porcelain.
